Various features have been put in place for the calendar booker to assist with shift work.
Out of hours working:
Your own start and end time can be entered for the current calendar view. This range can be outside the ‘Normal’ hours for the company. These can be set in the upper section 'Preferences'.
Bookings can be made outside the range of the normal company hours to accommodate booking time for shift workers.
Maximum booking size:
To stop 'all-day' bookings being generated automatically you can set a maximum booking size in Company settings, Default tab:
Crossing midnight:
If you have workers on a late shift it is possible to extend a booking from one day to the next, crossing over midnight.
